hi, im new to this site, looks great! thank you for all your knowledge and help John.
i have a studio space in Melbourne Australia with 3 tracking rooms and a control room.
i need help with addressing the acoustics in the control room.
At this stage the walls and roof are all bare painted plaster (26mm of sound check plasterboard with timber studs and sound-screen insulation). the floor is a concrete slab layered with (in order) acoustic underlay, 6mm concrete board, acoustic underlay and then finished with 8mm timber laminate flooring. not perfect i know but it is what i had available to me within my budget at the time.
i have attached an early floor plan to my facility to indicate the layout. the dimensions are not 100% accurate on the plan but lay out is accurate.
the dimensions of the control room internally is as follows;
4700L X 3810W X 2245H (metric millimeters)
extra info;
There will be a window installed on the left wall as you walk into the room, unknown in size as of yet (open to suggestions) but it will be roughly 2m X 1m in size and central to the wall in location.
control desk will take up 310W X 120D X 100H, there will also be a couch along the back wall.
any suggestions regarding baffles, defusers, internal construction etc would be greatly appreciated.
thanks again!
Josh.

Hi Josh. Please read the forum rules for posting (click here). You seem to be missing a couple of things! :)
How was that built? Is it a proper fully-decoupled 2-leaf isolation wall? Hard to say from that description. Do you have photos?At this stage the walls and roof are all bare painted plaster (26mm of sound check plasterboard with timber studs and sound-screen insulation).
Why the two sets of underlay, and why the fiber-cement board in the middle? Did you check with the manufacturer of the laminate, to make sure that is a suitable subfloor?the floor is a concrete slab layered with (in order) acoustic underlay, 6mm concrete board, acoustic underlay and then finished with 8mm timber laminate flooring. not perfect i know but it is what i had available to me within my budget at the time.
Close to Louden's third best ratio, number 7 on the list of "good" ratios... BUT! There's a problem: it isn't close enough. The length is almost exactly twice the height, so it fails one of the key tests for a critical listening room. I would try to fix that before you carry on. Or at least to work in some type of large, hard-backed, angled cloud to try to break the vertical modes a bit. Or soffit-mount the speakers. Or a combination. You'll also need major bass trapping on the front and rear walls. Also, I'm looking at the PDF plans, but I think they must be wrong, since they do not show any room with those dimensions.the dimensions of the control room internally is as follows; 4700L X 3810W X 2245H
Without seeing the exact room, with the correct dimensions, size, shape, layout, geometry, etc., it is impossible to say where you will need what type of treatment. Except to say that most types of diffuser are out of the question for that size room: it simply is not big enough to have enough distance between your head and the diffusers. So you are stuck with absorption only. That's not a bad thing, though. Basically, there isn't enough information in your post to be able to offer any useful advice. - Stuart -any suggestions regarding baffles, defusers, internal construction etc would be greatly appreciated.
